Winchester Defender Ammunition 357 Sig 125 Grain Bonded Jacketed Hollow Point Box of 20

Winchester Defender Ammunition 357 Sig 125 Grain Bonded Jacketed Hollow Point Box of 20 bonds the jacket to the core using Winchester’s proven fusion process for maximum weight retention. The bond resists separation even after it passes through denim or wallboard. This bullet reliably delivers deep, straight-line penetration alongside controlled expansion. Winchester engineers the hollow point cavity to open consistently across a wide velocity range, useful since barrel lengths vary between pistols.

Fusion-Bonded Weight Retention

As a result, shooters who want a dependable, widely available defensive round from a major manufacturer often choose this loading. The 125 grain bullet weight matches the traditional benchmark for this cartridge, balancing penetration, expansion, and felt recoil. Meanwhile, Winchester’s nickel-plated cases resist corrosion and feed smoothly, supporting reliability for a load kept chambered for long periods.
